Patented June 4, 1907.

. To all whom it may concern.-

Be it known that I, WALTER GROTHE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Shock-Reducers for Automobiles, of which the following is a full, clear, and exactdescription, reference being had to the accompanynng drawings.

The object of the invention is to reduce and substantially prevent the sudden and violent movement of an automobile body whichinsually takes place when the vehicle is rapidly going over a rough road, and to accomplish that result bysirnple and inexpensive means adapted for easy application to the vehicle.

The invention may be summarized as the combinations of parts shown in the drawing and hereinafter described and definitely pointed out in the claims.

In the drawing Figure l is a plan view of the rear part of the frame and running gear of an automobile. Fig. 2 is a side elevation of the part shown in Fig. 1. Fig. 3 is a sectional side elevation, on an enlarged scale, of the mechanism constituting-the present invention, together with those parts of the automobile to which it is to be attached. Fig. 4 is a. plan view ofthe mechanism shown in Fig. 3, omitting the part" of the automobile frame and the link connected thereto.

Referring to the parts by letters A A represent the two side mcm hers of the automobile frame upon which the pz'tssenger carrying body is to be secured. his frame is subpended on springs B, which are in turn secured by clips to the dead axles. The dead axles at the rear of the vehicle are cylindrical tubes which extend laterally from the casing J of the compensating gearing, and through which rotating live axles E pass. The dead axle at the iron t of an automobile is a transverse tubular member, to the ends of which are pivoted the knuckles which include the axle on which the front wheels rotate. Embracing each of these cylindrical dead axles C is a spring clamp D composed of between its head and the ear throtrh which' the screw loosely passes. This spring clamp has an inside facing G of leather or other suit able material which bears upon the tube 0. 'By turning up the screw .T, the pressure of the member into which said screws screw, is provided withan arm d". A link H is pivotally connected with this arm and with the automobile frame member A It will be understood that preferably four of these devices are to be employed on each automobile, two associated with the rear axle and two with the front axle. Endwise movements 20f these clamps upon the dead axles should be prevented, and this result may be attained by collars-F clamped u on the axles in substantial contact with bot sides of each spring clamp.

Ordinarily when an automobile is moving rapidly over a rough road, the resulting. movements of the body up and down are rapid and follow each other in quick succession. But,-when an automobile is equipped with the above described shock reducing mechanism, sudden relative movements of the axles and body are checked by the friction between the spring clamps and the dead axles, and, thereby, the extennand .violence of such movements are greatly reduced. Ou

the other hand, this shock reducing 1uechanism has no material effect in lessening the desired movement of the body, due to the flexing of tlr springs under normal conditions, that is to say, when the tendency to movement does not frequently occur, because a slow movement of the clamps upon the axles, corresponding with a slow movement of the bodyAnkes place easily.

Having described myinvention, I claim:

The combination, with frame and the dead axle of an automobile, of two substantially this clam upon the dead axle may be regu-' lated. T 1e upper clamp member, which otally connected with said arm and With'the automobile frame.
